New Kids on the Block/Backstreet Boys (NKOTBSB) Perform on Dick Clark's Rockin' New Year's Eve - HQ 

the best boyband NKOTB!!!!!!!!!!!

NKOTB paved the way for Backstreet Boys!

OMG my five year old daughter laughed at me and told me to calm down cause i went all crazy dancing the their songs and singing along love BSB and NKOTB im 23 and i love them. i told my five year old the way justin bieber is to you thats how they are to me lol

Without New Kids On The Block, there'd be no NSYNC & BSB. NKOTB was original boy band.

Being a NKOTB fan and somebody hopefully going to the NKOTBSB concert soon I realize something. I don't hate the BSB at all, it's the immature Backstreet FANS that still haven't grown up who hate on NKOTB for no reason that I can't stand one bit.

Loved the fact that Joey McIntyre sang his lines of Please Don't Go Girl and delighted us with his voice

New kids are the reason i want to dance. Bsb the reason i want to sing. Both are the reason i wanted to be in a boyband when i was younger. They rock

NKOTB the best! They Open the Road to boy bands....and always be un my hearth. 😘❤️❤️❤️❤️... love You guys!

two groups one generation still the best

I'm just so amazed that these guys can still pull it off!!! Just so freaking amazed!!!

As someone who grew up as a baby listening to NKOTB and fell in love with BSB when they first came out and I was in my preteens/teen years - I fucking lost my shit when I saw these two combine. I still can't get a grip. Lol I admit I fucking fan girl screamed my ass off and sang along. Nothing is better than the two bands you grew up listening to make a comeback "special" combination like this. NKOTBSB I fucking love every single one of you boys and it only gets better with Kevin around. Much love! And sorry about all the swearing. Lol I'm just really passionate about this combo. XD I love y'all!

Love how these 2 boy bands bonded

We really need slow jams back in the mainstream music... You can’t deny it, there’s nothing like dancing a slow ballad with your love.

What's up with the boyband war going in the comments? Both bands are great and obviously they respect each other, so why the fighting over who's better

I feel somewhat lucky that I grew up in the 80s with the new kids and then when I got to be more of an adult in the 90s I got to have the backstreet boys so I felt like I got the most best of both worlds and I thought that they collaborated amazingly together

they still sounded so good

I have no faves! I love BSB, NKOTB, Nsync, 98 degrees and alot more! They are all awesome!!

That was the best performance of that night! I just saw them in concert and they were freaking AWESOME!

Oh my God I have loved New Kids on the Block since it first came out has been listening to him and I love the Backstreet Boys so both of them to nap together is awesome that should do it more often

Tengo 17 años, y aunque no los disfrute en su época los disfruto ahora, son grandes artistas :)

These guys are just like wine, they get better and better.

I sat on my living room floor singing and dancing (even fist pumping at the end lol) to this while everyone laughed at me. This was by far the best thing to happen this year. I still smile when I watch this. Can't wait for tour!

I miss the 90's music and dance moves soo much!!!!

I have nothing against NKOTB, but BSB will always be #1 to me. Brian is my favorite and I just melt whenever I hear him sing.

Nkotb are the best ❤️‍🔥❤️‍🔥❤️‍🔥

La canción que me encanta, me recuerda mi niñez es: Please don't go girl. NKOTB lo mejor... Back Street también 🤗

best boy bands ever......period

I loved watching performance on new years eve it was awsome!!! fan of both boys, since I was a kid, through middle school, high school, and even now.

NKOTB all the way ! I wish they would perform "call it what you want"

LOVED IT! Still lookin' good!!!!

I will always love the new kids on the block i been a huge fan since i was 6 years old and I had everything my whole room was the new kids on the block. And now I'm 30 years old and i still love them. My favorite is Donnie wahlberg.

NKOB forever #1

Great performance im both a Backstreet boys and New kid on the block fan! can wait to see them in June. The are HOT!!!! espically Joey McIntyre, Brian Littrell and Jordan Knight

Jordan is the best!!! THE BEST!

Extremely Amazing!!! This is the show that the Superbowl should have yesterday.

NKOTB 4-ever! ♥

great collaboratio. between 2 boybands

New kids on the block and the backstreet boys at new York city having so much fun

Lots of handsomeness on that stage! Aging like fine wines, sirs!👏🏼👏🏼👏🏼👏🏼

but when the two groups perform together, they do create chemistry which makes great performance! you should go to their concert and feel it.

I have listened to the new kids on the block as a little girl and still listen to them. 😍

NKOTB IS THE BEST AF

i remembered my childhood and my teenage

This is the greatest collaboration of all time!!!!

Can not wait to see the concert in July in Columbus, OH is anyone else coming to Columbus, OH or around the U.S. to see these great guys. I was just born when NKOTB came out, and was in school when BSB came out, and my 1st concert on my own was BSB Black & Blue tour, lol. bring back flash backs! YAY.

wooo talento de sobra, lo que le falta a los cantantes de ahora.

I love when they sing "I'll never break your heart"

NKOTBSB in the D! June 16, 2011. Probably will be the best day i have all damn year!

NKOTB I remembered them when I was going to junior high and high school.

BSB !!! backstreet boys the best always !!! KTBSPA BSB4ver 💙💙💙💙💙

WHAT SURPRISES ME, IS THEY STILL SOUND SO AWESOME! haha.... ALL OF THEM... Just obviously sounds a SMIDGE older, but it's GREAT!

Época maravilhosa da minha juventude..

NKOTB is king of all boybands. BSB, a distant second place.

there should be a duo group just consisting of Nick and Jordan, best voices left

NKOTB will always be the best Boyband ever! Just if you would ask for how many fans they had, BSB never had. I don´t know if it is just such a good combination, because if the fans still talk against each other and still want to say which band or singer is better. I remember one interview back in the time, when one member of the BSB said, that only 1 or 2 members of the NKOTB could sing! Why to say that, if you think there´s no competition!

I LOVE this!!!!!!!!!!!!!!!!

Jordan tiene una voz maravillosa ; no hay punto de comparación 😊

I saw both of them in concert and they were both good up in Hershey Pennsylvania

omg I remember this NYE like it was yesterday....this one is for you, the one who was with me there!!

Amo essas boybands

Hermoso los dos grupos yo era de la epoca de lo NOKB

New Kids cantan excelente, wow.

New Kids Block And Back Street Boys they are amazing dancers and songs writers by god

I am travelling all the way from the UK to NY in June, just to see NKOTBSB!!!! I can't wait!!!

This performance would be an excellent Half Time Show in the Superbowl!

NKOTBSB BABY!! MY FAVE BSB MEMBER IS BRAIN & MY FAVE NKOTB MEMBER IS JON!!!! LOVE THEM!!!

Backstreet Boys forever!!!!!!!

new kids was the best in my younger years thank you for uploading

This is a 90's child dream.

Who else would there be? BSB is THE GREATEST OF ALL TIME AND NKOTB is right behind them. NKOTBSB is #5 on some huge Billboard List, of course, I could listen to them all day.

nkotb and bsb rock u guys are the best looking forward to your concert 11 june e

I LOVE NKOTB.... Been to the NKOTBSB tour twice this year and it makes me love them even more!! Next time just NKOTB please though BSB weren't bad at all!!

Muy buena musica y coreografias.......!!!!!! Una gra decada

i heart NKOTB

4:58 cracked when he said NEW YORK . OVERALLL BEST PERFORMANCE

The years have been good to Nick ;) I never listened to NKOTB a lot but this is a great thing with both groups. It would be awesome if Backstreet boys did this with Nsync. I loved both those groups growing up. BSB still my number 1 .

They look awesome at 40!!!!

Even though I love both groups, NKOTB were first and Joey was my first love. In my opinion New Kids outshine BSB any day. Joey and Jordan have voices and looks to die for, and Donnie brings so much wisdom and charisma, applying it in all he does. BSB are arguably more successful and I give them credit for that but I've been listening to NKOTB since I was 12. Nothing will ever take away that first love, Joey for me is it and I love him to bits xx

que musica por dios si habre bailado la coraografia en el aptio de mi casa graciassss¡¡

awesome !! Love you, Guys !!

I love the back street boys and the new kids on the block
